CMBINAI'ION MERRY-GO-ROUND AND TEETER.

'Go-Rolin and Toeter, of which the following tical movement o is aspeciiicatiQn- 'llus invention relates to an 'amusement device in whichare combined the rotating action of the merry-go-round and the verthesees'aw; and the object of the invention is a device of this character'adapted` for the use of children and in which the riders can motion incombination alternate up-and-down m vement by of suitable levers andratcets. The inventionv consists of `a suitable base upon which is pivctallymounted a sweep, and upon thebase is carried a ratchet, 'and pivot-armsare provided which are adapted to engage the ratchet, the said -armsbeing produce the rotary with the vertical actuated by suitable leversand links, and, as the ratclietis fixed, while the sweepz 'tos which theoperating-levers are pivoted is free to turn, a rotary motion willbegiven to the sweep.

wrought iron or steel, and j ournaled upon the same is a sweep 4. Thissweep I prefer to construct in sections, each section consisting of twoparallel timbers spaced apart so that a slot 5 will be left betweenthem, and the timbers also incline upwardly from their outer ends to thepivot-pi-n, and -at the point ofconnection o secured together by a metalcasting which is provided with a cap 6, and acasting-socket is providedin the castingand. ca to receive the pin 3, so that -the weight ci).

adjustable seats 7, which exten downwardly and inwardly 5 'and are heldtothe swee bolt 8, which passes througli the standard 7 and verticallythrough the slot 5 and on which .is threaded a' nut 9, which bears uponthe t'op of the sweep. A-sto pin 10 is car.- ried b each ofthe standar s7 and bears upon t e under side of the sweep. 'Upon' the upper end ofeach of the seat-standards 7 is aced a seat 11, and it'will be obviousthat so that the position of the'seaft with respect to the pivot-pin canbe varied. A The'inventio'n consists in the novel fea'- .tures ofconstruction hereinafter fully de- To further brace the arts, a truss 12is con? nected to the under si es of the sweep adjacent the meetingpoint of'the two sections andv overlapping-the said point, and the truss12 is longitudinally slotted, 'as shown at 13, and tov permit freeplaycand rotation of-the sweep' upon and about the pivot 3. T o'hold thesweep in a horizontal osition when not in use, a plate 14 is place u'and springs 15 are secure at 'their' inner ends to the said plate andattheir outer end s' to the under face of the truss '12. f

To provide for the rotation of the sweep about .the pivot-point 3, arms16,'and 17-.are pivoted upon the pin 3 at their innerends, and, as shownin 5, thearm 17 overlaps areduced end ortionof the arm 16 and alsopro'ects slight y into'n-undercut 18, formed in t e arin 16 adjafc'entthe pivot-pin 3. This prevents the inner end of the arm 17 from' ridingup upon the sides of the pivot-pin 3l I have shown -tl i provided uponthrough the slotl by means of a the two sections they are the sweepAbears upon the top of the said pin. I als jiprovide Qn'the pivot-pin 3f IOO ie arms-16 and .17 as being-f their under faces withawlsy 19,which engage theteeth o Etheratc et 2 5but it will be understood,of'iie,that the ratchet-teeth can be omittedand the device operated byfriction.

To operate the arms and 17 Ievers. 20

'80 .l by this manneroi securing the seat that it is adjustable alongthe sweep,

are ivotally connected at their lower ends to t e seat-standards 7 andprovided with suitable horizontal handle-bars 21 at their upper ends,the said levers projecting -upwardly through the slot and within easyreach of a child sittin upon the adjacent Each lever 2() is connected toone of the arms 16 17 by means of links 22 23, which links overlap andare fastened together by a pin 24, the overlapping ortions of the links22 and 23 being provide with a plurality of erforations and also withguideoops 2 his construction permits of the length of the links beingadjusted as is necessary to allow for sliding adjustment of the seats 11along the swee 4,and it will be obvious' that by allowing fieradjustment of the seats the seats can be so positioned with re spect tothejpivot-pin 3 that a difference in weight of the children using thedevice can be compensated for.v j

Adjacent the lowerends of the seat-standard 7 are' laced transverse pins26, extending upon eac side of the standard, which pins serve asfoot-rests. V

In operation the device can be used either as la seesaw or as a combinedmerry-goround and seesaw b operating the lever 20, and the operation othese levers remove the arms 16 and 17 in one direction, the pawls 19slidin upon the ratchetteeth,and when the lever is pulled in theopposite direction the pawls 19 will hold and the sweep will be given arotatory movement. This will not only cause the sweep to revolve, butwill also give a downward tendency `tothe end of the sweep from whichthe lever is being operated, and on account of this arrangement when oneoperator .is in a higher plane than the' other and pulls upon his leverthe action not only. produces a circular movement of the sweep, but alsogives a downward movement to his end of the sweep, and in this manner byalternately operating the ,levers 2l) a' combined rotatory andwavemotion may be oh tained, or when only one o crater works oneI of thelevers the repeate operation of the saidl lever will cause a rotationsullicicntly rapid so that the centrifugal force will hold the machinesteady, or that is in a comparatively horizontal plane, and this alonewill compensate for a considerable dillcrcnce in weight of the tworiders without changing the adjustment of the seats.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is

1. A device of the kind described comprising a central pivoted sweep,longitudinal slotted, a seat-standard extending throng said slot andslidably adjustable alon said slot, a seat carried by the said standar al'ever pivotally connected at its lower end to the said standard andalso projecting up'- wardly throu h the said slot, and means connectedto saidlever for rotating the sweep.

2. The combination with a pivoted sweep, longitudinally slotted, aseat-standard extending in said slot, and slidably adjustable therein, aseat upon the standard, a fixed disk concentric with the 'pivot-point ofthe sweep, an arm pivoted upon said disk, a lever ivoted to theseat-standard, adjustable inks connecting the lever to the arm and meanscarried by the arm adapted to engage the disk.

3. A device of the kind described comprising a base, a disk therein,apivoted pin on the disk, a sweep pivotally resting upon the saidpivot-pin, seats adjustably mounted upon the sweep, arms pivotallymounted upon .the pivot-pin, means carried by the arms adapted to engagethe periphery of the disk and means operatable'from the seats forpartially rotating said arms in opposite directions. i

` 4. A device of the kind described comprising a base, a pivot-pin, aratchet, a sweep pivotally mounted upon the ivot-pin adjacent theratchet, pawls carried l; the armsadapted to slide uponthe ratchet inone direction and to hold the arms stationary during a pull in theopposite direction, scat-standards slidably adjustable in the slot ofth(` sweep, seats carried by said standards, a lever pivotally connectedto each Aol" said standards, and adjustable links connecting 'saidlevers to the said arms, respectively, als :1nd for thc purpose selforth.
